6. Eduardo Is thinking of a non-unit fraction with a single digit denominator

netineya [11]

Answer:

The fraction is $\frac{1}{4}$ .

Step-by-step explanation:

Eduardo Is thinking of a non-unit fraction with a single-digit denominator.

Assuming the fraction to be $\frac{1}{x}$ .

When Eduardo multiplies his fraction by 5 he gets a mixed number and when he multiplies his fraction by 3 he can simplify the answer.

Therefore, the fraction chosen by Eduardo will be $\frac{1}{x}$ , where x is between 5 and 3.

So, the fraction is $\frac{1}{4}$ .

Again, when he multiplies his fraction by 4 he gets $(\frac{1}{4} \times 4) = 1$ which is a whole number. (Answer)
